Building a metal detector

WebIn order to meet the NIJ standard, a walkthrough metal detector must be able to detect a 6.35 mm (0.25 in) caliber pistol at a distance of up to 2.54 cm (1.0 in) from the surface of the body. The NIJ also has standards for duty gear, such as handcuffs, body armor, and batons. WebSo as you know a metal detector is essentially a radio that simply transmits Electromagnetic inducing Waves which induces eddy currents in a target which are transmitted back out of phase and the receiver coil picks this up amplifies the response and the control box does its magic converting this induced signal to a tone and id.
